The server currently only has two storage schemas - Anvil and Forgetful. If you don't set one explicitly, set Default or an unknown schema, Anvil will be used.
There is a slight possibility that our Anvil files are incompatible with some tools. I've run into some problems (files not aligned to 4KiB) when using Minutor with MCS worlds; but I think I've fixed those in the meantime. Is that MC Overviewer open-source? Can it be debugged to find the problem?
